Capacitance Leakage Current Measurement Techniques Using the Electrometer/High Resistance Meter
애플리케이션 노트
Capacitor leakage current is a crucial parameter that can be expressed in terms of insulation resistance. Accurate measurement requires the capacitor to be fully charged and stable at its test voltage, with error currents from dielectric absorption removed. The document provides best practices for safe measurement and protecting instruments from damage. It includes detailed explanations of leakage current components, measurement timing, and test equipment setup for both floating and grounded capacitors. Additionally, it offers tips to mitigate measurement instability and safety issues, such as using series resistors and PLC averaging. The B2985C/B2987C electrometer / high resistance meter is highlighted for its high voltage output and unmatched current measurement resolution, making it suitable for a wide range of capacitor types.
